Rezumat:

In the Letter we have constructed and investigated some properties of the Gazeau-Klauder quasi-coherent states for the Morse potential, previously deduced by Roy and Roy. We have focused our attention on the thermal states and we have found the analytical form of the diagonal P-representation of the density operator.
